To all whom t may concern:

Be it known that we, FREDERICK and JAMES TowNsoN, citizens ofthe UnitedStates residing at Pawtucket, in--the count of Providence and State-'ofRhode Islan ,i

have invented certain new and useful Improvcments in'Looms; and we dohereby' declare the following to be a full, clear, and exact descriptionof. the -inventiom-,such as will enable others skilled in .the arttowhich it appertains to make and use the same.

The invention relates to looms for weaving cord tire fabric consistingof comparatively heavy warp threads or cords bound togetherby very fine,weak and wldely spaced filling threads which servemerely to retain thecords vvin close parallel relation.

In rubberizing the fabric of the above character pre aratory toincorporating itin tires, it is su jected to the action of heavycalender rolls to which it is fed under comparatively heavy tension.Owing to the. weakness and wide spacing of the tine fill.

ing threads, the action of the rolls causes any comparatively loosecords or series of cords to creep along the fabric and bank up at thepoint where the fabric enters the'rolls untll suflicient slackaccumulates to cause a .fold

which enters the rolls and causes a ruptureof the fabric at this point.It is the ob- -ject of the present invention to-'weavev a cordtirefabric of the above character which shall be free from suchobjectionable loose cords or series of cords. This is accomplished bymaintaining a practically uniforml and regulated tension on each warpcord throughout theweaving. The means for securing this result comprisesmechanism for positively feeding in to the harness, dur- 1n unlformlength of each warp cord which is properly proportioned with relation tothe length of the fabric taken-up by the fabric take-up mechanism tosecure a uniforml stretch of each cord in successive sheds, andequalizing devices for maintaining a uniform tension on the cordsleadingto the feeding-in mechanism. Since the feeding-in mechanism feeds inythe same length of cord for each shed, and since a uniformtension ismaintained on each cord leading to the feeding-in mechanism, each cordwill be under they same tension in successive sheds and a-uniform fabricwill be? produced.

l- A The feeding-in l mechanism preferably C. HALL each cycle of theloom, a definite andy comprises a feeding-inroll .6r d rum over whichthe warp threads, pass'ss'i'de-by-side and about whichthey wrap toasufficient extent toprevent any slipping-over the sur-v face of theroll. The equalizing devices a weight suspended on each warp cord orthread and actlng to automatically take up any slack inthe cord and tomaintain a uniform light tension 'on it as it leads tov the feeding-inroll. By the use of takeupsof uniform weightan equal, as well as a uniiside lby side on the roll may be, .and prefera \ably1is, securedandcontin'ually maintained by thread spacing separators in the form of areedthrough which the threads lead to the roll. The thin plates of thereed separate the different threads and accuratelyv space them as theyare drawn forward by the' roll so that'; there is no danger of onethread riding on another and thus causing variations' in the tensiononthe threads. To further guard against anytendency of the threads toinfluence or vary the tension or pull on adjacent threads between the,feeding in roll and the harness thread spacing, separators in the formof a reed may be, and preferably are, arranged in front of Athe feedingin roll. The thin plates of this reed separate and spacethe threads andovercome any 4tendency of thethreads to ride orv cling on one another ontheir way to the harness in such manner ras to modify or vary thetension of such threads. The warp threads are lcd -to the equalizing andfeeding in' mechanisms from individual s ools, each of which carries asingle warp tiiread supply.

A'preferred form of the invention is illustrated in the accompanyingdrawings in which Fig. 1 is a vertical sectional View illustrating theinvention somewhat diagrammatically, Fig. 2 is a side elevation partlyin section showing so .much of a loom as is. necessary to illustrate theapplication of the invention thereto and Fig. 3 is a plan View showingthe mechanism foractuating the feedin in ro'll.

In t e drawings the invention is shown applied to a loom having theusual lay 2 60 preferably comprise a take-up in the form of I Y Theproper arrangement of the threads ,a set of lease rods 10 and are thusbrought into position side by side. From the lease rods l0 the threadspass to a second set of lease rods 12 and thence between the thin platesof the reed 14 whichfkeep themproperly separated and spaced and directthem side byl side to the feeding in mechanism. The devices formaintaining a uniform tension onthe warp threads'4 leading to thefeeding in mechanism are locatedk between the two sets of lease rods10"a`nd12 and consist of take-up Weights 16 suspended on the.

threads. The Weights are-in the form of Wires or rods which are providedWith eyes for the passage of the thread and are guided in holes in theguide plates 18 and 20. The rods play freely through the guide plates,thus taking upv any temporary slackness which might otherwise occur`between .the supply spools and the feeding in mechanism and maintain auniform light tension on each of the threads. The threads are,therefore, uniforml 4taut Whenengaged by the feeding in mec anism andwill be uniformly acted on thereby.

The feeding in mechanism shown comprises a feeding in roll 22Whieh maybe covered with sand or 'otherwise roughened to prevent slipping of thethreads thereon and two cooperating guide rolls 24 and 26 which causesthe threads to wrap nearly around the roll. The threads lead from thereed 14 .to the roll 24, and from the roll 26 tothe harl ness. On theway to the harness the threads .pass through areed 27 which serves` tomaintain themin proper spaced relation and to prevent such contactvbetween adjacent threads as y Wo-nld tend to influence or modify thetension thereon. The threads also pass through the usual lease rods 29.From the harness the threads pass through the lay to the previouslyWoven fabricv which kpasses over the breast beam28, around a fabrictake-up drum 30, over guide rolls 32, 34 and 36 to the cloth roll 38,..upon Which `it is Wound. The feedingjn'jroll is positively formly tautas they come to the feeding in roll, and are positively held andcontrolled thereby, each of the threads will be under a pre-determinedtension between the woven fabric and the feeding in roll, depending uponthe relation between the movements l given to the feeding in roll and tothe fabric take-up drum.

The rotation of the feeding in roll is preferably intermittent and sotimed that there is no feed of the threads during the passage of theshuttle through the sheds formed by the harness. As shown the feeding inroll is connected through gearing 40 with a ratchet Wheel 42, Which isengaged and actuated by.

'a pawl44 connected With the eccentric strap 46 engaging an eccentric 48carried by the lay operating shaft 50. The eccentric strap is formed on`the end ofa link 52 connected to the lever 54, which carries the pawl 56for actuating the ratchet wheel 58 on the end of the clothshaft 38. Thefabric take-up drum 30 is continuously driven through-gear,-

'ing 60 connecting the drum with a Worm Wheel 62, which is engaged by a,worm 64 ona shaft 66 driven through beveled gears 68 from the cam shaft70 of the loom. The Worm and Worm Wheel drive insures a uniform'pull onthe fabric and also positively holds the drum against reverse movementunder the tension on the fabric and Warp threads. l 1
